SPECIFICATION forming p art of Letters Patent No. 325,728, dated september 1885.

l Application filed December l5, 1884. (No model.)

To aZZ whom may concern:

Be it known that I, GUsrAv R. BRUCH- MANN, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Stills; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which 1o it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or iigures .of reference marked thereon, which form a part of this specification. My invention relates to improvementsin beer or mash stills for making high or VVlow proof alcohol, and pertains to that class in and by which the beer or mash is introduced while the process of distillation is going forward, whereby I am enabled to proceed with the work continuously without stopping to fill the still.

In the accompanying drawings, Figure l represents a longitudinal vertical section of my improved still. Fig. 2 is a horizontal sec.- tion drawn on line w x of Fig. 1. Fig. 3 is also a horizontal section drawn on line y y of Fig. l. Fig. 4 is a perspective of one of the valves I.

3o Like parts are referred to by the same reference-letters throughout the several views.

A is a vertically-arranged cylinder, which is lsubdivided into several compartments by the series of partitions B B. Mash or beer to be distilled enters the upper compartment, C,

through the pipe D, when it passes through the coil E and escapes through its discharge end upon the upper partition. As the fluid thus admitted rises to sufficient height it over- 4o iiows into the mouths of the tubes F F, through which it passes into the compartments next below until a suficient quantity has entered to bring it to the levelof the mouth of the next pipes F F below, (similar pipes, F F, being provided in each compartment,) when it Ilows through such pipe F in like manner from one compartment to another until the fluid thus admitted stands at a uniform depth corresponding to the height of the several 5o pipes F above the several partitions. This being done, steam is admitted through the M. The lower ends of the several pipes F pipe G, whenl it passes into the circular perforated pipe H, by which the steam is uni- `formly distributed around the bottom of the lower compartment. As the pressure of steam 55 increases in the lower compartment it raises the valves I in the several partitions, and thus passes up through the beer. The steam and beer are both thus admitted during the process of distilling. The vapor thus produced passes off through the vapor-pipe J to the condenser. The slop or non-vaporized substance lying below the upper ends of the pipes F passes from one compartment to another `from the highest to the lowest compart- 6 5 ment through the pipes F, when it escapes from the lowest compartment through the pipe terminate in a cup -shaped receptacle, S, which,

when full of beer, forms a trap which preventm.- y

the steam from escaping from one compartment to another through said pipes F, as it otherwise would do, instead of passing through the Vvalves I. The slop in passing out flows through the pipe M into the receptacle N,

when it buoys up the float O, whereby the valve P, attached thereto, is raised, thus permitting the slop to escape through the pipe Q. When desirous to treat the liquor which accumulates in the condenser, it is admitted through the pipe It, and from thence it flows of its own gravity from one compartment to another until it is uniformly distributed, as before mentioned, in the several compartments. T T are a seriesof cocks, by which the height 8 5 of the beer is ascertained, and in case thestill is clogged the place of the stoppage is located. The obj ect of the coil E is to retain the beer so that it will become heated before it is dis charged from the pipes, while the cool beer or mash in the coils cools the surrounding low-proof vapor in the upper compartment yand condenses it.-

The object of the pipe c is to permit the escape of vapor from the receptacle N as it fills, so that the beer may stand upon the same level in the receptacle N as it does in the cylinder A.

b is a rod by which the float A and valve l? are raised in case the valve becomes fast. it becomes necessary, in making repairs, &c., to remove the sediments lying below the mouth of the pipes F, such sediments are drawn off from all the compartments, from the highest to the lowest, inclusive, through the slidevalves K, when it escapes through the sloppipes L and Q. i

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a still, the combination of a cylinder, A, subdivided into a series of compartments by partitions B, provided with upward-opening steam valves I and downward extending ducts F, having their upper ends projecting above the upper surface of said partitions, and their lower ends terminating in recep-
